AArch64: Fix mv-cmpu-features.C test that fails on older glibc's [PR 122405]

Adds a definition of HWCAP_ATOMICS and HWCAP2_RNG in the test file for the
case that the glibc is old enough to not include them.

	PR target/122405

gcc/testsuite/ChangeLog:

	* g++.target/aarch64/mv-cpu-features.C: Add HWCAP_ATOMICS and
	HWCAP2_RNG defines.
